Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking facility and its vehicle turning device. More specifically, the present invention relates to a vehicle turning device that turns a vehicle that has entered into and exits a parking facility to change its front-rear direction, and a mechanical parking facility equipped with the vehicle turning device.

[0002]

2. Description of the Related Art As a parking facility having a vehicle turning device, for example, Japanese Patent No. 2 is used.
Those disclosed in Japanese Patent No. 711868 and Japanese Patent No. 2879516 are known. Each of these parking facilities has a turntable on the entry / exit floor, and further various sensors are arranged outside the turntable. These sensors are for determining whether or not the vehicle has entered the turntable and whether or not the vehicle has stopped within a predetermined range. If the vehicle is not stopped within the specified range, it is judged that the safety of the turning operation of the turntable or the lifting operation by the elevator is not ensured, or these operations are stopped, or the operation to change the stop position of the vehicle is performed. Done.

The sensor detects, for example, whether or not the vehicle body is present at the front and rear ends and substantially in the center of the predetermined stop range on the turntable. As described above, all of these sensors are fixed on the outside of the turntable, not on the turntable.

Therefore, it is only possible to detect the vehicle body when the vehicle gets in, that is, the vehicle body before the turntable turns. On the other hand, for example, when the driver of the vehicle forgets to pull the so-called side brake of the vehicle, the vehicle may move in the front-rear direction while turning the turntable. In order to stop the turning of the turntable and the driving of the elevator in such a situation, it is necessary to additionally install a sensor for detecting the vehicle body when the vehicle is stopped again after turning. This is because the front-back direction of the vehicle changes before and after turning. In addition, in order to detect inadvertent movement of the vehicle while the turntable is turning, an infinite number of sensors are theoretically necessary.

As a result, an increase in the number of parts causes an increase in equipment cost and an increase in maintenance cost. Furthermore, when installing a large number of detection devices, it is necessary to avoid the vehicle entry / exit path and the user entry / exit path, which greatly limits the degree of freedom in installation.

[0006] The present invention has been made to solve the above problems, and detects a vehicle or the like that has entered on a turning device in a parking facility from before the turning of the turning device to after the turning of the turning device by using a small number of detection mechanisms. It is an object of the present invention to provide a vehicle turning device capable of performing the above.

[0007]

A vehicle turning device of the present invention is a turning device for turning a vehicle, wherein an object on the turning device is placed in a portion of the turning device that turns integrally with the vehicle. A detection device for detecting is provided.

According to this structure, even if the turning device turns, the positional relationship between the detecting device and the vehicle does not change because the vehicle, the user and the like turn together with the detecting device. Therefore, it is not necessary to increase the number of detection devices to be installed regardless of the number of turning stop positions of the turning device. Moreover, it is possible to detect the displacement of the vehicle or the like during the turn without increasing the number of detecting devices. The object is
This means not only the vehicle but also the luggage of the user and the user himself / herself.

A turning table for placing a vehicle is provided, and the vehicle turning apparatus in which the detection device is placed on the turning table is preferable. This is because on the turning table, the degree of freedom of installation of the detection device is improved, such as the positional relationship with the mounted vehicle can be easily set.

Further, a turning device provided with a turning table, and a vehicle turning device in which the above-mentioned detecting device is arranged on a peripheral edge of the turning table is preferable. By arranging them on the peripheral edge, it is possible to detect as many things as possible on the turntable.

Further, disposed on the turning table,
An opening through which the pallet for mounting on the vehicle passes vertically,
The pallet support device is provided in the opening for moving to a working position for supporting the pallet and a non-working position for allowing the pallet to pass through the opening, and the detection device is located at least in the opening. A vehicle turning device which detects an object existing at the front end and an object existing at the rear end of the pallet is preferable.

Since it is possible to detect at least the front and rear ends of the pallet on the turning device, it is possible to detect the careless movement of the vehicle outside the predetermined range even while the turning device is turning.

The mechanical parking facility of the present invention is any one of the above-described vehicle turning devices for changing a front and rear direction of a parking space for accommodating a vehicle and a vehicle entering and leaving the parking space. It has and.

With this structure, it is not necessary to increase the number of detection devices to be installed regardless of the number of turning stop positions of the turning device. Moreover, it is possible to detect the displacement of the vehicle or the like during the turn without increasing the number of detecting devices.

It makes an angle of 48 ° with both directions. Therefore, the F direction and the H direction form an angle of 96 °.

As will be apparent by referring to FIG. 3 as well,
The turntable 11 is rotatably supported by a swivel support device 12a in a recess 12 formed in the floor of the entry / exit floor E. FIG. 3 is a plan view of the pallet turning device 10. A turning drive unit 13 having a motor 13a for turning the turntable 11 is disposed in the recess 12. Reference numeral 14 indicates an electric wiring space. In addition, an opening 15 is formed in the center of the turntable 11 so as to allow the pallet 2 to pass vertically. Further, a pallet support device 16 for advancing and retracting toward the opening 15 is arranged on the lower surface of the turntable 11.

The turntable 11 in the waiting state for warehousing has its opening 15 oriented in the F direction. The pallet support device 16 advances into the opening 15 and places the pallet 2 thereon. The height position of the pallet 2 at this time is slightly above the rail of the first lift 4. Pallet 2
When the vehicle M gets into the vehicle, the turntable 11 turns 48 ° to change the longitudinal direction of the pallet 2 from the arrow F direction to the G direction. Then, when the pallet support device 16 is slowly retracted from the opening 15, the pallet 2 is placed on the rail 9 of the first lift 4. Then, the first lift 4 descends to lower the pallet 2 to the height of the lateral transfer path 3 at any stage. At this time, the other pallet 2 in the lateral transfer path 3 is connected by the male and female connector 7. Next, the pallet row is horizontally transferred by a horizontal transfer drive device (not shown), and the pallet group is cyclically moved together with the lifting of both lifts 4 and 5.

At the time of leaving the warehouse, the turntable 11 has its opening 15 oriented in the G direction, and the pallet support device 16 is retracted under the turntable 11. When the pallet 2 lifted by the first lift 4 passes through the opening 15 upwards, the pallet support device 16 advances and the first lift 4 slightly descends. Thus palette 2
When the pallet is placed on the pallet support device 16, the turntable 1
1 rotates 48 ° to change the longitudinal direction of the pallet 2 from the arrow G direction to the H direction.

FIG. 4A shows IVA-IVA in FIG.
It is a sectional view taken along the line and FIG. 4B is a side view of the turntable 11. As shown in FIG. 3 and FIG. 4, a plurality of detection devices 17 for detecting the vehicle M, the protective fence 18, and the like that have boarded on the turntable 11 are provided on the outer peripheral edge of the upper surface of the turntable 11. ing. The protective fences 18 are housed on the undersides of the left and right sides of each pallet 2, and when the vehicle gets on the pallet, the operator confirms that the door of the vehicle is closed and operates an operation panel (not shown). By doing so, the pallet 2 is configured to advance upward from both sides.

The detectors 17 are all columns 19 standing on the turntable 11 and the columns 19 and the protective fence 18 described above.
Etc. and the photoelectric sensor 20 attached to the same. The sensor is not limited to the photoelectric sensor, and another type of sensor may be used. The first detection device 17a is the turntable 1
1 is installed at a position for transmitting and receiving a beam along the front end side of the pallet 2 when located in the opening 15. The second detection device 17b is installed at a position for transmitting and receiving a beam along the rear end side of the pallet 2 at the same position on the turntable 11. These detection devices 17a and 17b detect whether the front and rear ends of the vehicle that has entered the vehicle are protruding from the front and rear ends of the pallet 2. Further, the third detection device 17c is installed at a position for transmitting and receiving a beam between the pillar 19 and the protection fence 18 in a standing state. It is possible to determine that the vehicle door is closed by detecting the protection fence 18 in a state where the body is raised. This third detection device 17
c is installed on both the left and right sides of the opening 15, and the light receiving device or the issuing device of the third detecting device 17c is attached to the protective fence 18. The fourth detection device 17d is installed at a position for transmitting and receiving a beam along the diagonal line of the pallet. In the fourth detection device 17d, the column 19 of the sensor 20
The mounting height is set slightly higher than the so-called one-box car roof. As a result, it is determined whether the rear door of the one-box car is still flipped upward.

In FIG. 3, the state of the turntable 11 in which the pallet 2 is oriented in the G direction is shown by a solid line together with the detection device 17, and the state in which the pallet is oriented in the F direction and the H direction is indicated by a two-dot chain line. Although the detection device 17 is not shown in the state of being oriented in the F direction and the H direction, it is naturally in the state of being rotated by 48 ° from the G direction.

Each of the detection devices 17 is installed at a position outside the vehicle entry / exit path. The vehicle entrance / exit path is a path that extends along the longitudinal direction of the opening 15 of the turntable 11 and has a width substantially equal to the width of the opening.
Further, the mounting position of the sensor 20 on the support column 19 is adjusted to, for example, the height position where the front end portion or the rear end portion of a general vehicle exists. For example, the height at which the bumper exists. Further, if it is a detection device that confirms whether or not there is a person on the turntable 11, it is a height position at which it can be detected whether it is an adult or a child. Further, if these objects cannot be reliably detected only by the pair of sensors 20, a plurality of sensors 20 are attached to one support column 19 with different height positions, and the plurality of pairs of sensors ensure reliable detection. You may be able to guarantee. That is, the number and height positions of the sensors 20 attached to one support or one protection fence 18 are not limited. The sensor 20 may be attached to each of the height positions that match the shapes of the front and rear ends of various vehicles. Further, the number of detection devices 17 installed is not limited to the above. The above-mentioned detection device is an example. Although not shown, a detection device for transmitting and receiving beams may be provided along the left and right sides of the pallet 2 other than the above.
The detection device may be provided at a position on the turntable other than the positions where humans and other objects can be detected.

As described above, since all the detection devices 17 are installed on the turntable 11, even if the turntable 11 turns, the vehicle and the detection device 17 turn together, so that the detection devices 17 and The positional relationship with the vehicle does not change. Therefore, it is not necessary to increase the number of detection devices to be installed regardless of the number of turning stop positions of the turntable 11. Moreover, the displacement of the vehicle during the turn can be detected without increasing the number of detecting devices.

In the embodiment described above, a multi-layer circulation type parking facility using a lift is taken as an example, but the present invention is not particularly limited to this type of parking facility. It may be an elevator-type multi-level parking facility or another parking facility. In short, the present invention is applicable to any parking facility that includes a vehicle turning device that turns vehicles that are loaded and unloaded, and that can include a detection device in a portion of the vehicle turning device that turns together with the vehicle. Can be applied. Further, the turning device is not particularly limited to one having a turntable.
